Well, I do dislike first impressions because of how judgmental people can be. I would love to take apart the facts of his arguments, but he is just writing opinions and stating features. I'd be wrong to disagree with features, and I dislike his opinions. I believe they are not based off of experience with Buzz but based off of previously held ideals about social networking sites the author has claimed he dislikes. He is applying his view on one thing automatically to another without giving it a shot. He hasn't even given it a couple of days.
Picking apart arguments based on their content seems to get a better reception than attacking their author.
